Connection to the cooling circuit

Notice

Damage due to faulty sealing

Failure to observe the provisions for sealing the connections can result in damage to the motor and the entire system.

  • The cooling connections may only be sealed via the end faces of the water connections
  • Do not use conical screw connections or sealants in the thread (liquid sealant, Teflon tape, hemp, etc.) for sealing
  • The usable thread depth and the maximum tightening torque in aluminum must be taken into account

For the connection of the cooling hoses we recommend push-in fittings with male thread:

Coil unit

Male thread

AL804x

M5

AL806x-1xxx

G 1/8 “

 

Connection to the cooling circuit 1:
►Remove the plug [1] at the front of the coil unit

AL804x:

►Remove the plug on the opposite side of the coil unit
Connection to the cooling circuit 2:
►Screw the threaded push-in fittings [2] into the holes provided

AL804x:

►Screw in the threaded push-in fittings on the opposite side of the coil unit

Notice

Shortened service life of the cooling hoses due to algae formation

Algae can form in the cooling system if the wrong hoses are chosen. This can shorten the service life of the cooling hoses and reduce the performance of the motor.

  • Use opaque cooling hoses to connect the water cooling system
  • Add suitable chemical additives to the coolant

For connecting the threaded push-in fittings, we recommend the following cooling hose sizes:

Connection to the cooling circuit 3:
►Insert the cooling hoses [3] into the threaded push-in fittings

AL804x:

►Connect cooling hoses at the opposite side of the coil unit
